我在模态结构中有一个表单,可以在其中收集用户的一些信息,之后,我希望将该信息提交到发布请求中,以便可以在python中进行处理。
问题是我需要首先检查用户是否实际输入了信息,所以我不会得到空值。
我正在使用.preventDefault()
来停止提交并检查值。只要我不使用preventDefault
,该程序就可以正常发布,并且在使用时实际上也不会发布。
问题是,通过所有条件后,它应该发布但不执行,而且我也不知道为什么。
以下是格式的代码:
<form id="forminout" action="/in_out" method="post">
<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" id="incomeModal">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Add your new income</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body" id="new_incomes">
<div style="padding:3%">
<input step=".01" type="number" class="form-control input-sm" name="incoming" min="0" placeholder="0">
<select class="incomselect" name="incomeselects" style="height:30px;">
<option selected disabled>This income is coming from?</option>
<option value="rent">Rents</option>
<option value="salary">Salary</option>
<option value="invest_reveneu">Investments reveneus</option>
<option value="others">Others</option>
</select>
<select class="incomdate" name="incomedate" style="height: 30px;">
<option selected disabled>Incoming date</option>
<option value=5>1 - 5</option>
<option value=10>6 - 10</option>
<option value=15>11 - 15</option>
<option value=20>16 - 20</option>
<option value=25>21 - 25</option>
<option value=31>26 - 31</option>
</select>
</div>
</div>
<div class="modal-footer">
<button class="btn btn-primary" id="addinbutt" type="submit">Save changes</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</form>
哪个工作正常,因为该帖子实际上正在发生。
这是发布请求的“简化”代码:
$("document").ready(function(){
$("form").on("submit", function(e){
errors = 0;
e.preventDefault();
if (errors==0)
{
document.getElementById("#forminout").submit();
}
})
})
在这种情况下,假设我需要检查的所有实际条件都可以,errors==0
条件只是为了简化起见。
我就是无法发布。
答案 0 :(得分:0)
解决方案:写this.submit()
或e.target.submit()
而不是doc.getElById().submit()
$("document").ready(function(){
$("#forminout").on("submit", function(e){
e.preventDefault();
// ur conditions ...
this.submit();
})
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="forminout" action="/in_out" method="post">
<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" id="incomeModal">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Add your new income</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body" id="new_incomes">
<div style="padding:3%">
<input step=".01" type="number" class="form-control input-sm" name="incoming" min="0" placeholder="0">
<select class="incomselect" name="incomeselects" style="height:30px;">
<option selected disabled>This income is coming from?</option>
<option value="rent">Rents</option>
<option value="salary">Salary</option>
<option value="invest_reveneu">Investments reveneus</option>
<option value="others">Others</option>
</select>
<select class="incomdate" name="incomedate" style="height: 30px;">
<option selected disabled>Incoming date</option>
<option value=5>1 - 5</option>
<option value=10>6 - 10</option>
<option value=15>11 - 15</option>
<option value=20>16 - 20</option>
<option value=25>21 - 25</option>
<option value=31>26 - 31</option>
</select>
</div>
</div>
<div class="modal-footer">
<button class="btn btn-primary" id="addinbutt" type="submit">Save changes</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</form>
您甚至可以根据e
参数编写此代码:
$("document").ready(function(){
$("#forminout").on("submit", function(e){
e.preventDefault();
// ur conditions ...
e.target.submit();
})
})
